One way to do it would be like this:

 param(
       [Parameter(Position=0)][String]$Vlan,
       [Parameter(ValueFromRemainingArguments=$true)][String[]]$Hosts
    ) ...

This would allow multiple hosts to be entered with spaces.

On Xampp edit apache config

1. Click Apache 'config'
2. Select 'httpd-ssl.conf'
3. Look for 'Listen 443', change it to 'Listen 4430'

I do appreciate the answer of "Chang She", really, but the iterrows() function takes long time on large dataset. I faced that issue and I came to this.

# First, reset_index to make the index a column
a = a.reset_index().rename(columns={'index':'duplicated_idx'})

# Get a longer series with exploded cells to rows
series = pd.DataFrame(a['var1'].str.split('/')
                      .tolist(), index=a.duplicated_idx).stack()

# New df from series and merge with the old one
b = series.reset_index([0, 'duplicated_idx'])
b = b.rename(columns={0:'var1'})

# Optional & Advanced: In case, there are other columns apart from var1 & var2
b.merge(
    a[a.columns.difference(['var1'])],
    on='duplicated_idx')

# Optional: Delete the "duplicated_index"'s column, and reorder columns
b = b[a.columns.difference(['duplicated_idx'])]

If you're specifically looking for a click outside the element but still within the parent, you can use

<div class="parent" @click.self="onParentClick">
  <div class="child"></div>
</div>

I use this for modals.

While what you want to accomplish may be useful, there is another option which I believe you might be overlooking that is much more simple.

You are correct, the Bootstrap tables act strangely when you have columns which are not fixed height. However, there is a bootstrap class created to combat this issue and perform responsive resets.

simply create an empty <div class="clearfix"></div> before the start of each new row to allow the floats to reset and the columns to return to their correct positions.

here is a bootply.

Another intuitive solution could be:

class Post
{
    public $title;
    public $date;
}

$posts = array();

$posts[0] = new Post();
$posts[0]->title = 'post sample 1';
$posts[0]->date = '1/1/2021';

$posts[1] = new Post();
$posts[1]->title = 'post sample 2';
$posts[1]->date = '2/2/2021';

foreach ($posts as $post) {
  echo 'Post Title:' . $post->title . ' Post Date:' . $post->date . "\n";
}

As a complement to other's answers, it's possible to desaturate an image half the way on FF without SVG's matrix's headaches:

<feColorMatrix type="saturate" values="$v" />

Where $v is between 0 and 1. It's equivalent to filter:grayscale(50%);.

Live example:

.desaturate {_x000D_
    filter: url("#desaturate");_x000D_
    -webkit-filter: grayscale(50%);_x000D_
}_x000D_
figcaption{_x000D_
    background: rgba(55, 55, 136, 1);_x000D_
    padding: 4px 98px 0 18px;_x000D_
    color: white;_x000D_
    display: inline-block;_x000D_
    border-top-left-radius: 8px;_x000D_
    border-top-right-radius: 100%;_x000D_
    font-family: "Helvetica";_x000D_
}

Reference on MDN

A struct (without a typedef) often needs to (or should) be with the keyword struct when used.

struct A;                      // forward declaration
void function( struct A *a );  // using the 'incomplete' type only as pointer

If you typedef your struct you can leave out the struct keyword.

typedef struct A A;          // forward declaration *and* typedef
void function( A *a );

Note that it is legal to reuse the struct name

Try changing the forward declaration to this in your code:

typedef struct context context;

It might be more readable to do add a suffix to indicate struct name and type name:

typedef struct context_s context_t;

Try this formula

=SMALL((A1,C1,E1),INDEX(FREQUENCY((A1,C1,E1),0),1)+1)

Both SMALL and FREQUENCY functions accept "unions" as arguments, i.e. single cell references separated by commas and enclosed in brackets like (A1,C1,E1).

So the formula uses FREQUENCY and INDEX to find the number of zeroes in a range and if you add 1 to that you get the k value such that the kth smallest is always the minimum value excluding zero.

I'm assuming you don't have negative numbers.....

Im not the person to tell you about speed and memory usage, but looking at a switch statment is a hell of a lot easier to understand then a large if statement (especially 2-3 months down the line)

Using Python 3.2:

x = {"b":4, "a":3, "c":1}
for i in sorted(x.values()):
    print(list(x.keys())[list(x.values()).index(i)])

On Route change it will scroll to the top of the page.

 $scope.$on('$routeChangeSuccess', function () {
      window.scrollTo(0, 0);
  });

put this code on your controller.

I use this:

var app = express();

app
.use(function(req, res, next){
    res.header('Access-Control-Allow-Origin', '*');
    res.header('Access-Control-Allow-Headers', 'X-Requested-With');
    next();
})
.options('*', function(req, res, next){
    res.end();
})
;

h.readFiles('controllers').forEach(function(file){
  require('./controllers/' + file)(app);
})
;

app.listen(port);
console.log('server listening on port ' + port);

this code assumes that your controllers are located in the controllers directory. each file in this directory should be something like this:

module.exports = function(app){

    app.get('/', function(req, res, next){
        res.end('hi');
    });

}

Try this code to watch for, and report, a possible net::ERR_INSECURE_RESPONSE

I was having this issue as well, using a self-signed certificate, which I have chosen not to save into the Chrome Settings. After accessing the https domain and accepting the certificate, the ajax call works fine. But once that acceptance has timed-out or before it has first been accepted, the jQuery.ajax() call fails silently: the timeout parameter does not seem help and the error() function never gets called.

As such, my code never receives a success() or error() call and therefore hangs. I believe this is a bug in jquery's handling of this error. My solution is to force the error() call after a specified timeout.

This code does assume a jquery ajax call of the form jQuery.ajax({url: required, success: optional, error: optional, others_ajax_params: optional}).

Note: You will likely want to change the function within the setTimeout to integrate best with your UI: rather than calling alert().

const MS_FOR_HTTPS_FAILURE = 5000;
$.orig_ajax = $.ajax;
$.ajax = function(params)
{
  var complete = false;
  var success = params.success;
  var error = params.error;
  params.success = function() {
    if(!complete) {
      complete = true;
      if(success) success.apply(this,arguments);
    }
  }
  params.error = function() {
    if(!complete) {
      complete = true;
      if(error) error.apply(this,arguments);
    }
  }
  setTimeout(function() {
    if(!complete) {
      complete = true;
      alert("Please ensure your self-signed HTTPS certificate has been accepted. "
        + params.url);
      if(params.error)
        params.error( {},
          "Connection failure",
          "Timed out while waiting to connect to remote resource. " +
          "Possibly could not authenticate HTTPS certificate." );
    }
  }, MS_FOR_HTTPS_FAILURE);

  $.orig_ajax(params);
}

I haven't tested on other Laravel versions but on 5.3-5.8 you reference the query parameter as if it were a member of the Request class.

1. Url

http://example.com/path?page=2

2. In a route callback or controller action using magic method Request::__get()

Route::get('/path', function(Request $request){
 dd($request->page);
}); 

//or in your controller
public function foo(Request $request){
 dd($request->page);
}

//NOTE: If you are wondering where the request instance is coming from, Laravel automatically injects the request instance from the IOC container
//output
"2"

3. Default values

We can also pass in a default value which is returned if a parameter doesn't exist. It's much cleaner than a ternary expression that you'd normally use with the request globals

   //wrong way to do it in Laravel
   $page = isset($_POST['page']) ? $_POST['page'] : 1; 

   //do this instead
   $request->get('page', 1);

   //returns page 1 if there is no page
   //NOTE: This behaves like $_REQUEST array. It looks in both the
   //request body and the query string
   $request->input('page', 1);

4. Using request function

$page = request('page', 1);
//returns page 1 if there is no page parameter in the query  string
//it is the equivalent of
$page = 1; 
if(!empty($_GET['page'])
   $page = $_GET['page'];

The default parameter is optional therefore one can omit it

5. Using Request::query()

While the input method retrieves values from entire request payload (including the query string), the query method will only retrieve values from the query string

//this is the equivalent of retrieving the parameter
//from the $_GET global array
$page = $request->query('page');

//with a default
$page = $request->query('page', 1);

6. Using the Request facade

$page = Request::get('page');

//with a default value
$page = Request::get('page', 1);

You can read more in the official documentation https://laravel.com/docs/5.8/requests

In my case, the problem was coming from the execution of WinSAT.exe (located in System32 folder). I disabled it and issue solved.

To turn it off:

1. Start > Task Scheduler (taskschd.msc)
2. Find Task Scheduler (Local)
3. Task Scheduler Library
4. Microsoft > Windows > Maintenance
5. Right click WinSAT
6. Select disable.

The Reference

Also, suppress it from Task Manager or simply reboot your machine.

Point: In this situation (when the problem comes from WinSAT) emulator works (with poor performance) when you use Software - GLES 2.0 and works with very very poor performance when you use Hardware - GLES 2.0.

You can always format a date by extracting the parts and combine them using string functions:

var date = new Date();_x000D_
var dateStr =_x000D_
  ("00" + (date.getMonth() + 1)).slice(-2) + "/" +_x000D_
  ("00" + date.getDate()).slice(-2) + "/" +_x000D_
  date.getFullYear() + " " +_x000D_
  ("00" + date.getHours()).slice(-2) + ":" +_x000D_
  ("00" + date.getMinutes()).slice(-2) + ":" +_x000D_
  ("00" + date.getSeconds()).slice(-2);_x000D_
console.log(dateStr);

To get the lines that contain the texts 8768, 9875 or 2353, use:

^.*(8768|9875|2353).*$

What it means:

^                      from the beginning of the line
.*                     get any character except \n (0 or more times)
(8768|9875|2353)       if the line contains the string '8768' OR '9875' OR '2353'
.*                     and get any character except \n (0 or more times)
$                      until the end of the line

If you do want the literal * char, you'd have to escape it:

^.*(\*8768|\*9875|\*2353).*$

Try to use getElementById() or getElementsByName() to access a specific element and then to use innerHTML property:

<html>
    <body>
        <div id="myDiv1"></div>
        <div id="myDiv2"></div>
    </body>

    <script type="text/javascript">
        var myDiv1 = document.getElementById("myDiv1");
        var myDiv2 = document.getElementById("myDiv2");

        myDiv1.innerHTML = "<b>Content of 1st DIV</b>";
        myDiv2.innerHTML = "<i>Content of second DIV element</i>";
    </script>
</html>

If you try appending the number like, say listName.append(4) , this will append 4 at last. But if you are trying to take <int> and then append it as, num = 4 followed by listName.append(num), this will give you an error as 'num' is of <int> type and listName is of type <list>. So do type cast int(num) before appending it.

This can be achieved by doing

(a2 & a1) == a2

This creates the intersection of both arrays, returning all elements from a2 which are also in a1. If the result is the same as a2, you can be sure you have all elements included in a1.

This approach only works if all elements in a2 are different from each other in the first place. If there are doubles, this approach fails. The one from Tempos still works then, so I wholeheartedly recommend his approach (also it's probably faster).

Currently, the eyedropper tool is not working in my version of Chrome (as described above), though it worked for me in the past. I hear it is being updated in the latest version of Chrome.

However, I'm able to grab colors easily in Firefox.

1. Open page in Firefox
2. Hamburger Menu -> Web Developer -> Eyedropper
3. Drag eyedropper tool over the image... Click.
   Color is copied to your clipboard, and eyedropper tool goes away.
4. Paste color code

In case you cannot get the eyedropper tool to work in Chrome, this is a good work around.
I also find it easier to access :-)

Try using

<table  border="1" cellspacing="0" cellpadding="0" class="template-table" 
style="table-layout: fixed; width: 100%"> 

as table style along with

<td style="word-break:break-word">long text</td>

for td it works for normal/real scenario text with words, not for random typed letters without gaps

You are just updating the value of i in the loop. The value of i should also be added each time.

It is never a good idea to update the value of i inside the for loop. The for loop index should only be used as a counter. In your case, changing the value of i inside the loop will cause all sorts of confusion.

Create variable total that holds the sum of the numbers up to i.

So

 for (int i = 0; i < positiveInteger; i++)
        total += i;

This will override console.log function when the url does not contain localhost. You can replace the localhost with your own development settings.

// overriding console.log in production
if(window.location.host.indexOf('localhost:9000') < 0) {
    console.log = function(){};
}

Here is the code snippet which will work for sure. You can visit below link for working jsFiddle and explainantion in detail. How to locate multiple addresses on google maps with perfect zoom

var infowindow = new google.maps.InfoWindow();  
google.maps.event.addListener(marker, 'mouseover', (function(marker) {  
           return function() {  
               var content = address;  
               infowindow.setContent(content);  
               infowindow.open(map, marker);  
           }  
         })(marker));  

You should be looking for the second tr that has the td that equals ' Color Digest ', then you need to look at either the following sibling of the first td in the tr, or the second td.

Try the following:

//tr[td='Color Digest'][2]/td/following-sibling::td[1]

or

//tr[td='Color Digest'][2]/td[2]

I had the same problem. Go to Project Properties -> Deployment Assemplbly and add jstl jar

I like to do it with a static method in the second activity:

private static final String EXTRA_GAME_ID = "your.package.gameId";

public static void start(Context context, String gameId) {
    Intent intent = new Intent(context, SecondActivity.class);
    intent.putExtra(EXTRA_GAME_ID, gameId);
    context.startActivity(intent);
}

@Override
protected void onCreate(Bundle savedInstanceState) {
    ... 
    Intent intent = this.getIntent();
    String gameId = intent.getStringExtra(EXTRA_GAME_ID);
}

Then from your first activity (and for anywhere else), you just do:

SecondActivity.start(this, "the.game.id");

Linebreaks are not the same under windows/linux/mac. You should use System.getProperties with the attribute line.separator.

According to the documentation of the Item property:

Sets or returns an item for a specified key in a Dictionary object.

In your case, you don't have an item whose key is 1 so doing:

s = d.Item(i)

actually creates a new key / value pair in your dictionary, and the value is empty because you have not used the optional newItem argument.

The Dictionary also has the Items method which allows looping over the indices:

a = d.Items
For i = 0 To d.Count - 1
    s = a(i)
Next i

If you just want to change it once, you can specify the 'from' header in command line, eg:

mutt -e 'my_hdr From:[email protected]'

my_hdr is mutt's command of providing custom header value.

One last word, don't be evil!

You can use :

composer self-update --2

To update to 2.0.8 version (Latest stable version)

This solved the issue for me:

pip install -I --upgrade psutil --force

Afterwards just uninstall psutil with the new version and hop you can suddenly install the older version (:

At first, the problem is because you did't put any parameter for mysqli_error. I can see that it has been solved based on the post here. Most probably, the next problem is cause by wrong file path for the included file.. .

Are you sure this code

$myConnection = mysqli_connect("$db_host","$db_username","$db_pass","$db_name") or die ("could not connect to mysql");

is in the 'scripts' folder and your main code file is on the same level as the script folder?

MySQL does not support the renaming of a database through its command interface at the moment, but you can rename the database if you have access to the directory in which MySQL stores its databases. For default MySQL installations this is usually in the Data directory under the directory where MySQL was installed. Locate the name of the database you want to rename under the Data directory and rename it. Renaming the directory could cause some permissions issues though. Be aware.

Note: You must stop MySQL before you can rename the database

I would recommend creating a new database (using the name you want) and export/import the data you need from the old to the new. Pretty simple.

I would say you have an indentation problem, at least as you wrote it here:

while not os.path.exists(file + "_" + str(i) + extension):
   i+=1
   print "Already 2x exists..."
   print "Renaming"
   shutil.copy(path, file + "_" + str(i) + extension)

should be:

while os.path.exists(file + "_" + str(i) + extension):
    i+=1
print "Already 2x exists..."
print "Renaming"
shutil.copy(path, file + "_" + str(i) + extension)

Check this out, please!

I made the following bash script in order to clone ALL of my Bitbucket (user) repositories to GitHub as private repositories.

Requirements:

• jq (command-line JSON processor) | MacOS: brew install jq

Steps:

1. Go to https://github.com/settings/tokens and create an access token. We only need the "repo" scope.

2. Save the move_me.sh script in a working folder and edit the file as needed.

3. Don't forget to CHMOD 755

4. Run! ./move_me.sh

5. Enjoy the time you have saved.

Notes:

• It will clone the BitBucket repositories inside the directory the script resides (your working directory.)

• This script does not delete your BitBucket repositories.

Need to move to public repositories on GitHub?

Find and change the "private": true to "private": false below.

Moving an organization's repositories?

Checkout the developer guide, it's a couple of edits away.

Happy moving.

Select Product from formula bar in your answer cell.

Select cells you want to multiply.

Had the same problem. I was passing a non-const reference of custom class and the constructor complained (some tuple template errors). Replaced the reference with pointer and it worked.

if you want only the background-image to be affected, you can use a linear gradient to do that, just like this:

  background: linear-gradient(rgba(0, 0, 0, .5), rgba(0, 0, 0, .5)), url(IMAGE_URL);

If you want it darker, make the alpha value higher, else you want it lighter, make alpha lower

Element inherits from Node, in the same way that Dog inherits from Animal.

An Element object "is-a" Node object, in the same way that a Dog object "is-a" Animal object.

Node is for implementing a tree structure, so its methods are for firstChild, lastChild, childNodes, etc. It is more of a class for a generic tree structure.

And then, some Node objects are also Element objects. Element inherits from Node. Element objects actually represents the objects as specified in the HTML file by the tags such as <div id="content"></div>. The Element class define properties and methods such as attributes, id, innerHTML, clientWidth, blur(), and focus().

Some Node objects are text nodes and they are not Element objects. Each Node object has a nodeType property that indicates what type of node it is, for HTML documents:

1: Element node
3: Text node
8: Comment node
9: the top level node, which is document

We can see some examples in the console:

> document instanceof Node
  true

> document instanceof Element
  false

> document.firstChild
  <html>...</html>

> document.firstChild instanceof Node
  true

> document.firstChild instanceof Element
  true

> document.firstChild.firstChild.nextElementSibling
  <body>...</body>

> document.firstChild.firstChild.nextElementSibling === document.body
  true

> document.firstChild.firstChild.nextSibling
  #text

> document.firstChild.firstChild.nextSibling instanceof Node
  true

> document.firstChild.firstChild.nextSibling instanceof Element
  false

> Element.prototype.__proto__ === Node.prototype
  true

The last line above shows that Element inherits from Node. (that line won't work in IE due to __proto__. Will need to use Chrome, Firefox, or Safari).

By the way, the document object is the top of the node tree, and document is a Document object, and Document inherits from Node as well:

> Document.prototype.__proto__ === Node.prototype
  true

Here are some docs for the Node and Element classes:
https://developer.mozilla.org/en-US/docs/DOM/Node
https://developer.mozilla.org/en-US/docs/DOM/Element

This is just namespacing. Look at the examples for reference - you need to either use the namespaced class or reference it absolutely, for example:

use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;

//Load composer's autoloader
require 'vendor/autoload.php';

Jeff Bridgman is correct. All you need is
background: url('pic.jpg')
and this assumes that pic is in the same folder as your html.

Also, Roberto's answer works fine. Tested in Firefox, and IE. Thanks to Raptor for adding formatting that displays full picture fit to screen, and without scrollbars... In a folder f, on the desktop is this html and a picture, pic.jpg, using your userid. Make those substitutions in the below:

<html>
<head>
    <style>
        body {

        background: url('file:///C:/Users/userid/desktop/f/pic.jpg') no-repeat center center fixed;

        background-size: cover; /* for IE9+, Safari 4.1+, Chrome 3.0+, Firefox 3.6+ */
        -webkit-background-size: cover; /* for Safari 3.0 - 4.0 , Chrome 1.0 - 3.0 */
        -moz-background-size: cover; /* optional for Firefox 3.6 */ 
        -o-background-size: cover; /* for Opera 9.5 */
        margin: 0; /* to remove the default white margin of body */
        padding: 0; /* to remove the default white margin of body */
        overflow: hidden;
             }
    </style>
</head>
<body>
hello
</body>
</html>

I'm guessing that you actually want Omega to be a string containing an uppercase omega? In that case, you can write:

var Omega = '\u03A9';

(Because Ω is the Unicode character with codepoint U+03A9; that is, 03A9 is 937, except written as four hexadecimal digits.)

Or:

gem update `gem outdated | cut -d ' ' -f 1`

That's basically a set of 2 simultaneous equations:

x*y = a
X+y = b

(using the mathematical convention of x and y for the variables to solve and a and b for arbitrary constants).

But the solution involves a quadratic equation (because of the x*y), so depending on the actual values of a and b, there may not be a solution, or there may be multiple solutions.

If you're getting source in Content Use the following method

try
{
    var response = restClient.Execute<List<EmpModel>>(restRequest);

    var jsonContent = response.Content;

    var data = JsonConvert.DeserializeObject<List<EmpModel>>(jsonContent);

    foreach (EmpModel item in data)
    {
        listPassingData?.Add(item);
    }
}
catch (Exception ex)
{
    Console.WriteLine($"Data get mathod problem {ex} ");
}

First, follow the instructions in this question to squash everything to a single commit. Then make a forced push to the remote:

$ git push origin +master

And optionally delete all other branches both locally and remotely:

$ git push origin :<branch>
$ git branch -d <branch>

There is also strptime() which expects exactly one format:

$a = strptime('22-09-2008', '%d-%m-%Y');
$timestamp = mktime(0, 0, 0, $a['tm_mon']+1, $a['tm_mday'], $a['tm_year']+1900);

Solution:

To your secondary question

var elem1 = $('#elem1'),
    elem2 = $('#elem2'),
    elem3 = $('#elem3');

You can use the variable as the replacement of selector.

elem1.css({'display':'none'}); //will work

In the below case selector is already stored in a variable.

$(elem1,elem2,elem3).css({'display':'none'}); // will not work

http://railscasts.com/episodes/279-understanding-the-asset-pipeline

This railscast (Rails Tutorial video on asset pipeline) helps a lot to explain the paths in assets pipeline as well. I found it pretty useful, and actually watched it a few times.

The solution I chose is @Lee McAlilly's above, but this railscast helped me to understand why it works. Hope it helps!

I had this issue also, I solved it instantly with this answer from a similar thread

In my case, I didn't want to delete the dependent record on key deletion. If this is the case in your situation just simply change the Boolean value in the migration to false:

AddForeignKey("dbo.Stories", "StatusId", "dbo.Status", "StatusID", cascadeDelete: false);

Chances are, if you are creating relationships which throw this compiler error but DO want to maintain cascade delete; you have an issue with your relationships.

As a tangential note, one case where the ability to have multiple .gitignore files is very useful is if you want an extra directory in your working copy that you never intend to commit. Just put a 1-byte .gitignore (containing just a single asterisk) in that directory and it will never show up in git status etc.

My case is, it doesn't work wherever I call it, no matter I path the file or not, if I open it with powershell.

but it works if I open it with cmd.

I did exactly what you're looking for in a very simple way. It is perfectly smooth in Google Chrome and Opera, and almost perfect in Firefox and Safari. Not tested in IE.

function newTab(url)
{
    var tab=window.open("");
    tab.document.write("<!DOCTYPE html><html>"+document.getElementsByTagName("html")[0].innerHTML+"</html>");
    tab.document.close();
    window.location.href=url;
}

Fiddle : http://jsfiddle.net/tFCnA/show/

Explanations:
Let's say there is windows A1 and B1 and websites A2 and B2.
Instead of opening B2 in B1 and then return to A1, I open B2 in A1 and re-open A2 in B1.
(Another thing that makes it work is that I don't make the user re-download A2, see line 4)

^{The only thing you may doesn't like is that the new tab opens before the main page.}

public class Test {

public static void main(String args[]) {

  for(int x = 10; x < 20; x = x+1) {
     if(x==15)
         break;
     System.out.print("value of x : " + x );
     System.out.print("\n");
  }
}
}

The last and the best one. i.e LOGICAL AND

  if (foo != null && foo.bar()) {
    etc...
}

Because in logical &&

it is not necessary to know what the right hand side is, the result must be false

Prefer to read :Java logical operator short-circuiting

This is what I wrote when I needed to split a DataFrame. I considered using Andy's approach above, but didn't like that I could not control the size of the data sets exactly (i.e., it would be sometimes 79, sometimes 81, etc.).

def make_sets(data_df, test_portion):
    import random as rnd

    tot_ix = range(len(data_df))
    test_ix = sort(rnd.sample(tot_ix, int(test_portion * len(data_df))))
    train_ix = list(set(tot_ix) ^ set(test_ix))

    test_df = data_df.ix[test_ix]
    train_df = data_df.ix[train_ix]

    return train_df, test_df


train_df, test_df = make_sets(data_df, 0.2)
test_df.head()

You need to use Arrow function ()=> ES6 feature to preserve this context within setTimeout.

// var that = this;                             // no need of this line
this.messageSuccess = true;

setTimeout(()=>{                           //<<<---using ()=> syntax
      this.messageSuccess = false;
 }, 3000);

Pig is useful for ETL kind of workloads generally speaking. For example set of transformations you need to do to your data every day.

Hive shines when you need to run adhoc queries or just want to explore data. It sometimes can act as interface to your visualisation Layer ( Tableau/Qlikview).

Both are essential and serve different purpose.

This directive works as a [routerLink] replacement. All you have to do is to replace your [routerLink] usages with [link]. It works with ctrl+click, cmd+click, middle click.

import {Directive, HostListener, Input} from '@angular/core'
import {Router} from '@angular/router'
import _ from 'lodash'
import qs from 'qs'

@Directive({
  selector: '[link]'
})
export class LinkDirective {
  @Input() link: string

  @HostListener('click', ['$event'])
  onClick($event) {
    // ctrl+click, cmd+click
    if ($event.ctrlKey || $event.metaKey) {
      $event.preventDefault()
      $event.stopPropagation()
      window.open(this.getUrl(this.link), '_blank')
    } else {
      this.router.navigate(this.getLink(this.link))
    }
  }

  @HostListener('mouseup', ['$event'])
  onMouseUp($event) {
    // middleclick
    if ($event.which == 2) {

      $event.preventDefault()
      $event.stopPropagation()
      window.open(this.getUrl(this.link), '_blank')
    }
  }

  constructor(private router: Router) {}

  private getLink(link): any[] {
    if ( ! _.isArray(link)) {
      link = [link]
    }

    return link
  }

  private getUrl(link): string {
    let url = ''

    if (_.isArray(link)) {
      url = link[0]

      if (link[1]) {
        url += '?' + qs.stringify(link[1])
      }
    } else {
      url = link
    }

    return url
  }
}

There's a JSON section in the PHP's documentation. You'll need PHP 5.2.0 though.

As of PHP 5.2.0, the JSON extension is bundled and compiled into PHP by default.

If you don't, here's the PECL library you can install.

<?php
    $arr = array ('a'=>1,'b'=>2,'c'=>3,'d'=>4,'e'=>5);

    echo json_encode($arr); // {"a":1,"b":2,"c":3,"d":4,"e":5}
?>

Use the join method from the Array type.

a.value = [a, b, c, d, e, f];
var stringValueYouWant = a.join();

The join method will return a string that is the concatenation of all the array elements. It will use the first parameter you pass as a separator - if you don't use one, it will use the default separator, which is the comma.

Is there a way to set the session timeout programatically

There are basically three ways to set the session timeout value:

• by using the session-timeout in the standard web.xml file ~or~
• in the absence of this element, by getting the server's default session-timeout value (and thus configuring it at the server level) ~or~
• programmatically by using the HttpSession. setMaxInactiveInterval(int seconds) method in your Servlet or JSP.

But note that the later option sets the timeout value for the current session, this is not a global setting.

The only classes that can be static are inner classes. The following code works just fine:

public class whatever {
    static class innerclass {
    }
}

The point of static inner classes is that they don't have a reference to the outer class object.

Upon installation, the Android SDK generates a debug signing certificate for you in a keystore called debug.keystore. The Eclipse plug-in uses this certificate to sign each application build that is generated.

Unfortunately a debug certificate is only valid for 365 days. To generate a new one you must delete the existing debug.keystore file. Its location is platform dependent - you can find it in Preferences - Android - Build - Default debug keystore.

In newer versions of MySQL connectors the default tables are also listed if catalog is not passed

        DatabaseMetaData dbMeta = con.getMetaData();
        //con.getCatalog() returns database name
        ResultSet rs = dbMeta.getTables(con.getCatalog(), "", null, new String[]{"TABLE"});
        ArrayList<String> tables = new ArrayList<String>();
        while(rs.next()){
            String tableName = rs.getString("TABLE_NAME");
            tables.add(tableName);
        }
        return tables;

If I had to do this with a regex, I'd do it like this:

s = re.sub(r'\.jpg$', '', s)

This is a solution where you have many fields in your table and don't want to get a finger cramp from typing all the fields, just type the ones needed :)

How to copy some rows into the same table, with some fields having different values:

1. Create a temporary table with all the rows you want to copy
2. Update all the rows in the temporary table with the values you want
3. If you have an auto increment field, you should set it to NULL in the temporary table
4. Copy all the rows of the temporary table into your original table
5. Delete the temporary table

Your code:

CREATE table temporary_table AS SELECT * FROM original_table WHERE Event_ID="155";

UPDATE temporary_table SET Event_ID="120";

UPDATE temporary_table SET ID=NULL

INSERT INTO original_table SELECT * FROM temporary_table;

DROP TABLE temporary_table

General scenario code:

CREATE table temporary_table AS SELECT * FROM original_table WHERE <conditions>;

UPDATE temporary_table SET <fieldx>=<valuex>, <fieldy>=<valuey>, ...;

UPDATE temporary_table SET <auto_inc_field>=NULL;

INSERT INTO original_table SELECT * FROM temporary_table;

DROP TABLE temporary_table

Simplified/condensed code:

CREATE TEMPORARY TABLE temporary_table AS SELECT * FROM original_table WHERE <conditions>;

UPDATE temporary_table SET <auto_inc_field>=NULL, <fieldx>=<valuex>, <fieldy>=<valuey>, ...;

INSERT INTO original_table SELECT * FROM temporary_table;

As creation of the temporary table uses the TEMPORARY keyword it will be dropped automatically when the session finishes (as @ar34z suggested).

This was resolved. It turns out our IT Staff was correct. Both TLS 1.1 and TLS 1.2 were installed on the server. However, the issue was that our sites are running as ASP.NET 4.0 and you have to have ASP.NET 4.5 to run TLS 1.1 or TLS 1.2. So, to resolve the issue, our IT Staff had to re-enable TLS 1.0 to allow a connection with PayTrace.

So in short, the error message, "the client and server cannot communicate, because they do not possess a common algorithm", was caused because there was no SSL Protocol available on the server to communicate with PayTrace's servers.

UPDATE: Please do not enable TLS 1.0 on your servers, this was a temporary fix and is not longer applicable since there are now better work-arounds that ensure strong security practices. Please see accepted answer for a solution. FYI, I'm going to keep this answer on the site as it provides information on what the problem was, please do not down-vote.

The port is available here: java.rmi.registry.Registry.REGISTRY_PORT (1099)

showInventory(player); is passing a type as parameter. That's illegal, you need to pass an object.

For example, something like:

player p;
showInventory(p);  

I'm guessing you have something like this:

int main()
{
   player player;
   toDo();
}

which is awful. First, don't name the object the same as your type. Second, in order for the object to be visible inside the function, you'll need to pass it as parameter:

int main()
{
   player p;
   toDo(p);
}

and

std::string toDo(player& p) 
{
    //....
    showInventory(p);
    //....
}

Here is an alternative implementation using XMLTABLE that allows for casting to different data types:

select 
  xmltab.txt
from xmltable(
  'for $text in tokenize("a,b,c", ",") return $text'
  columns 
    txt varchar2(4000) path '.'
) xmltab
;

... or if your delimited strings are stored in one or more rows of a table:

select 
  xmltab.txt
from (
  select 'a;b;c' inpt from dual union all
  select 'd;e;f' from dual
) base
inner join xmltable(
  'for $text in tokenize($input, ";") return $text'
  passing base.inpt as "input"
  columns 
    txt varchar2(4000) path '.'
) xmltab
  on 1=1
;

You can also use truncate.

truncate table table_name;

Cell padding

is used for formatting purpose which is used to specify the space needed between the edges of the cells and also in the cell contents. The general format of specifying cell padding is as follows:

< table width="100" border="2" cellpadding="5">

The above adds 5 pixels of padding inside each cell .

Cell Spacing:

Cell spacing is one also used f formatting but there is a major difference between cell padding and cell spacing. It is as follows: Cell padding is used to set extra space which is used to separate cell walls from their contents. But in contrast cell spacing is used to set space between cells.

This article covers various ways of concatenating strings in SQL, including an improved version of your code which doesn't XML-encode the concatenated values.

SELECT ID, abc = STUFF
(
    (
        SELECT ',' + name
        FROM temp1 As T2
        -- You only want to combine rows for a single ID here:
        WHERE T2.ID = T1.ID
        ORDER BY name
        FOR XML PATH (''), TYPE
    ).value('.', 'varchar(max)')
, 1, 1, '')
FROM temp1 As T1
GROUP BY id

To understand what's happening, start with the inner query:

SELECT ',' + name
FROM temp1 As T2
WHERE T2.ID = 42 -- Pick a random ID from the table
ORDER BY name
FOR XML PATH (''), TYPE

Because you're specifying FOR XML, you'll get a single row containing an XML fragment representing all of the rows.

Because you haven't specified a column alias for the first column, each row would be wrapped in an XML element with the name specified in brackets after the FOR XML PATH. For example, if you had FOR XML PATH ('X'), you'd get an XML document that looked like:

<X>,aaa</X>
<X>,bbb</X>
...

But, since you haven't specified an element name, you just get a list of values:

,aaa,bbb,...

The .value('.', 'varchar(max)') simply retrieves the value from the resulting XML fragment, without XML-encoding any "special" characters. You now have a string that looks like:

',aaa,bbb,...'

The STUFF function then removes the leading comma, giving you a final result that looks like:

'aaa,bbb,...'

It looks quite confusing at first glance, but it does tend to perform quite well compared to some of the other options.

If you use Maven:

poi => poi-ooxml in artifactId

    <dependency>
        <groupId>org.apache.poi</groupId>
        <artifactId>poi-ooxml</artifactId>
        <version>3.12</version>
    </dependency>

Collation defines how you sort and compare string values

For example, it defines how to deal with

• accents (äàa etc)
• case (Aa)
• the language context:
  • In a French collation, cote < côte < coté < côté.
  • In the SQL Server Latin1 default , cote < coté < côte < côté
• ASCII sorts (a binary collation)

You may have moved on by now, but... as far as I know there's no way to delete a history entry (or state).

One option I've been looking into is to handle the history yourself in JavaScript and use the window.history object as a carrier of sorts.

Basically, when the page first loads you create your custom history object (we'll go with an array here, but use whatever makes sense for your situation), then do your initial pushState. I would pass your custom history object as the state object, as it may come in handy if you also need to handle users navigating away from your app and coming back later.

var myHistory = [];

function pageLoad() {
    window.history.pushState(myHistory, "<name>", "<url>");

    //Load page data.
}

Now when you navigate, you add to your own history object (or don't - the history is now in your hands!) and use replaceState to keep the browser out of the loop.

function nav_to_details() {
    myHistory.push("page_im_on_now");
    window.history.replaceState(myHistory, "<name>", "<url>");

    //Load page data.
}

When the user navigates backwards, they'll be hitting your "base" state (your state object will be null) and you can handle the navigation according to your custom history object. Afterward, you do another pushState.

function on_popState() {
    // Note that some browsers fire popState on initial load,
    // so you should check your state object and handle things accordingly.
    // (I did not do that in these examples!)

    if (myHistory.length > 0) {
        var pg = myHistory.pop();
        window.history.pushState(myHistory, "<name>", "<url>");

        //Load page data for "pg".
    } else {
        //No "history" - let them exit or keep them in the app.
    }
}

The user will never be able to navigate forward using their browser buttons because they are always on the newest page.

From the browser's perspective, every time they go "back", they've immediately pushed forward again.

From the user's perspective, they're able to navigate backwards through the pages but not forward (basically simulating the smartphone "page stack" model).

From the developer's perspective, you now have a high level of control over how the user navigates through your application, while still allowing them to use the familiar navigation buttons on their browser. You can add/remove items from anywhere in the history chain as you please. If you use objects in your history array, you can track extra information about the pages as well (like field contents and whatnot).

If you need to handle user-initiated navigation (like the user changing the URL in a hash-based navigation scheme), then you might use a slightly different approach like...

var myHistory = [];

function pageLoad() {
    // When the user first hits your page...
    // Check the state to see what's going on.

    if (window.history.state === null) {
        // If the state is null, this is a NEW navigation,
        //    the user has navigated to your page directly (not using back/forward).

        // First we establish a "back" page to catch backward navigation.
        window.history.replaceState(
            { isBackPage: true },
            "<back>",
            "<back>"
        );

        // Then push an "app" page on top of that - this is where the user will sit.
        // (As browsers vary, it might be safer to put this in a short setTimeout).
        window.history.pushState(
            { isBackPage: false },
            "<name>",
            "<url>"
        );

        // We also need to start our history tracking.
        myHistory.push("<whatever>");

        return;
    }

    // If the state is NOT null, then the user is returning to our app via history navigation.

    // (Load up the page based on the last entry of myHistory here)

    if (window.history.state.isBackPage) {
        // If the user came into our app via the back page,
        //     you can either push them forward one more step or just use pushState as above.

        window.history.go(1);
        // or window.history.pushState({ isBackPage: false }, "<name>", "<url>");
    }

    setTimeout(function() {
        // Add our popstate event listener - doing it here should remove
        //     the issue of dealing with the browser firing it on initial page load.
        window.addEventListener("popstate", on_popstate);
    }, 100);
}

function on_popstate(e) {
    if (e.state === null) {
        // If there's no state at all, then the user must have navigated to a new hash.

        // <Look at what they've done, maybe by reading the hash from the URL>
        // <Change/load the new page and push it onto the myHistory stack>
        // <Alternatively, ignore their navigation attempt by NOT loading anything new or adding to myHistory>

        // Undo what they've done (as far as navigation) by kicking them backwards to the "app" page
        window.history.go(-1);

        // Optionally, you can throw another replaceState in here, e.g. if you want to change the visible URL.
        // This would also prevent them from using the "forward" button to return to the new hash.
        window.history.replaceState(
            { isBackPage: false },
            "<new name>",
            "<new url>"
        );
    } else {
        if (e.state.isBackPage) {
            // If there is state and it's the 'back' page...

            if (myHistory.length > 0) {
                // Pull/load the page from our custom history...
                var pg = myHistory.pop();
                // <load/render/whatever>

                // And push them to our "app" page again
                window.history.pushState(
                    { isBackPage: false },
                    "<name>",
                    "<url>"
                );
            } else {
                // No more history - let them exit or keep them in the app.
            }
        }

        // Implied 'else' here - if there is state and it's NOT the 'back' page
        //     then we can ignore it since we're already on the page we want.
        //     (This is the case when we push the user back with window.history.go(-1) above)

Use a generator function to generate an iterator.

def foo_gen():
    n = 0
    while True:
        n+=1
        yield n

Then use it like

foo = foo_gen().next
for i in range(0,10):
    print foo()

If you want an upper limit:

def foo_gen(limit=100000):
    n = 0
    while n < limit:
       n+=1
       yield n

If the iterator terminates (like the example above), you can also loop over it directly, like

for i in foo_gen(20):
    print i

Of course, in these simple cases it's better to use xrange :)

Here is the documentation on the yield statement.

If you ran into this issue when using TypeScript, you may need to add skipLibCheck: true in your tsconfig.json file.

A process consists of at least one thread (think of the main function). Multi threaded code will just spawn more threads. Mutexes are used to create locks around shared resources to avoid data corruption / unexpected / unwanted behaviour. Basically it provides for sequential execution in an asynchronous setup - the requirement for which stems from non-const non-atomic operations on shared data structures.

A vivid description of what mutexes would be the case of people (threads) queueing up to visit the restroom (shared resource). While one person (thread) is using the bathroom easing him/herself (non-const non-atomic operation), he/she should ensure the door is locked (mutex), otherwise it could lead to being caught in full monty (unwanted behaviour)

It may be "better" to not use attach at all. On the plus side, you can save some typing if you use attach. Let's say your dataset is called mydata and you have variables called v1, v2, and v3. If you don't attach mydata, then you will type mean(mydata$v1) to get the mean of v1. If you do attach mydata, then you will type mean(v1) to get the mean of v1. But, if you don't detach the mydata dataset (every time), you'll get the message about the objects being masked going forward.

Solution 1 (assuming you want to attach):

1. Use detach every time.
2. See Dan Tarr's response if you already have the data attached (and it may be in the global environment several times). Then, in the future, use detach every time.

Solution 2

Don't use attach. Instead, include the dataset name every time you refer to a variable. The form is mydata$v1 (name of data set, dollar sign, name of variable).

As for me, I used solution 1 a lot in the past, but I've moved to solution 2. It's a bit more typing in the beginning, but if you are going to use the code multiple times, it just seems cleaner.

First, I can give you the answer for one table:

The trouble with all these INTO OUTFILE or --tab=tmpfile (and -T/path/to/directory) answers is that it requires running mysqldump on the same server as the MySQL server, and having those access rights.

My solution was simply to use mysql (not mysqldump) with the -B parameter, inline the SELECT statement with -e, then massage the ASCII output with sed, and wind up with CSV including a header field row:

Example:

 mysql -B -u username -p password database -h dbhost -e "SELECT * FROM accounts;" \
 | sed "s/\"/\"\"/g;s/'/\'/;s/\t/\",\"/g;s/^/\"/;s/$/\"/;s/\n//g"

"id","login","password","folder","email" "8","mariana","xxxxxxxxxx","mariana","" "3","squaredesign","xxxxxxxxxxxxxxxxx","squaredesign","[email protected]" "4","miedziak","xxxxxxxxxx","miedziak","[email protected]" "5","Sarko","xxxxxxxxx","Sarko","" "6","Logitrans Poland","xxxxxxxxxxxxxx","LogitransPoland","" "7","Amos","xxxxxxxxxxxxxxxxxxxx","Amos","" "9","Annabelle","xxxxxxxxxxxxxxxx","Annabelle","" "11","Brandfathers and Sons","xxxxxxxxxxxxxxxxx","BrandfathersAndSons","" "12","Imagine Group","xxxxxxxxxxxxxxxx","ImagineGroup","" "13","EduSquare.pl","xxxxxxxxxxxxxxxxx","EduSquare.pl","" "101","tmp","xxxxxxxxxxxxxxxxxxxxx","_","[email protected]"

Add a > outfile.csv at the end of that one-liner, to get your CSV file for that table.

Next, get a list of all your tables with

mysql -u username -ppassword dbname -sN -e "SHOW TABLES;"

From there, it's only one more step to make a loop, for example, in the Bash shell to iterate over those tables:

 for tb in $(mysql -u username -ppassword dbname -sN -e "SHOW TABLES;"); do
     echo .....;
 done

Between the do and ; done insert the long command I wrote in Part 1 above, but substitute your tablename with $tb instead.

Using without [::-1] or reversed -

def reverse(text):
    result = []
    for index in range(len(text)-1,-1,-1):
        c = text[index]
        result.append(c)
    return ''.join(result)

print reverse("python!")

Eclipse is recommending that you declare the type of the HashMap because that enforces some type safety. Of course, it sounds like you're trying to avoid type safety from your second part.

If you want to do the latter, try declaring map as HashMap<String,Object>.

Old topic, but I was recently affected by this.

Using a class "row-fluid" instead of "row" worked fine for me but I'm not sure if it's fully supported going forward.

So after reading Why does the bootstrap .row has a default margin-left of -30px I just used the <div> (without any row class) and it behaved exactly like <div class="row-fluid">

Another (simpler) Linux solution:

rm -r `find /path/to/foo -name .svn`

What you can do is set specific width and height to your iframe (for example these could be equal to your window dimensions) and then applying a scale transformation to it. The scale value will be the ratio between your window width and the dimension you wanted to set to your iframe.

E.g.

<iframe width="1024" height="768" src="http://www.bbc.com" style="-webkit-transform:scale(0.5);-moz-transform-scale(0.5);"></iframe>

Let look into a sample git repo to verify if your branch (master) is up to date with origin/master.

Verify that local master is tracking origin/master:

$ git branch -vv
* master a357df1eb [origin/master] This is a commit message

More info about local master branch:

$ git show --summary
commit a357df1eb941beb5cac3601153f063dae7faf5a8 (HEAD -> master, tag: 2.8.0, origin/master, origin/HEAD)
Author: ...
Date:   Tue Dec 11 14:25:52 2018 +0100

    Another commit message

Verify if origin/master is on the same commit:

$ cat .git/packed-refs | grep origin/master
a357df1eb941beb5cac3601153f063dae7faf5a8 refs/remotes/origin/master

We can see the same hash around, and safe to say the branch is in consistency with the remote one, at least in the current git repo.

Here's yet another idea - this method allows to specify any working week and holidays.

The idea here is that we find the core of the date range from the first first working day of the week to the last weekend day of the week. This enables us to calculate the whole weeks easily (without iterating over all of the dates). All we need to do then is to add the working days that fall before the start and end of this core range.

public static int CalculateWorkingDays(
    DateTime startDate, 
    DateTime endDate, 
    IList<DateTime> holidays, 
    DayOfWeek firstDayOfWeek,
    DayOfWeek lastDayOfWeek)
{
    // Make sure the defined working days run contiguously
    if (lastDayOfWeek < firstDayOfWeek)
    {
        throw new Exception("Last day of week cannot fall before first day of week!");
    }

    // Create a list of the days of the week that make-up the weekend by working back
    // from the firstDayOfWeek and forward from lastDayOfWeek to get the start and end
    // the weekend
    var weekendStart = lastDayOfWeek == DayOfWeek.Saturday ? DayOfWeek.Sunday : lastDayOfWeek + 1;
    var weekendEnd = firstDayOfWeek == DayOfWeek.Sunday ? DayOfWeek.Saturday : firstDayOfWeek - 1;
    var weekendDays = new List<DayOfWeek>();

    var w = weekendStart;
    do {
        weekendDays.Add(w);
        if (w == weekendEnd) break;
        w = (w == DayOfWeek.Saturday) ? DayOfWeek.Sunday : w + 1;
    } while (true);


    // Force simple dates - no time
    startDate = startDate.Date;
    endDate = endDate.Date;

    // Ensure a progessive date range
    if (endDate < startDate)
    {
        var t = startDate;
        startDate = endDate;
        endDate = t;
    }

    // setup some working variables and constants
    const int daysInWeek = 7;           // yeah - really!
    var actualStartDate = startDate;    // this will end up on startOfWeek boundary
    var actualEndDate = endDate;        // this will end up on weekendEnd boundary
    int workingDaysInWeek = daysInWeek - weekendDays.Count;

    int workingDays = 0;        // the result we are trying to find
    int leadingDays = 0;        // the number of working days leading up to the firstDayOfWeek boundary
    int trailingDays = 0;       // the number of working days counting back to the weekendEnd boundary

    // Calculate leading working days
    // if we aren't on the firstDayOfWeek we need to step forward to the nearest
    if (startDate.DayOfWeek != firstDayOfWeek)
    {
        var d = startDate;
        do {
            if (d.DayOfWeek == firstDayOfWeek || d >= endDate)
            {
                actualStartDate = d;
                break;  
            }
            if (!weekendDays.Contains(d.DayOfWeek))
            {
                leadingDays++;
            }
            d = d.AddDays(1);
        } while(true);
    }

    // Calculate trailing working days
    // if we aren't on the weekendEnd we step back to the nearest
    if (endDate >= actualStartDate && endDate.DayOfWeek != weekendEnd)
    {
        var d = endDate;
        do {
            if (d.DayOfWeek == weekendEnd || d < actualStartDate)
            {
                actualEndDate = d;
                break;  
            }
            if (!weekendDays.Contains(d.DayOfWeek))
            {
                trailingDays++;
            }
            d = d.AddDays(-1);
        } while(true);
    }

    // Calculate the inclusive number of days between the actualStartDate and the actualEndDate
    var coreDays = (actualEndDate - actualStartDate).Days + 1;
    var noWeeks =  coreDays / daysInWeek;

    // add together leading, core and trailing days
    workingDays +=  noWeeks * workingDaysInWeek;
    workingDays += leadingDays;
    workingDays += trailingDays;

    // Finally remove any holidays that fall within the range.
    if (holidays != null)
    {
        workingDays -= holidays.Count(h => h >= startDate && (h <= endDate));
    }

    return workingDays;
}

You may also consider the ToolStripButton control if you don't mind hosting it in a ToolStripContainer. I think it can natively support pressed and unpressed states.

There is no Linq ForEach extension. However, the List class has a ForEach method on it, if you're willing to use the List directly.

For what it's worth, the standard foreach syntax will give you the results you want and it's probably easier to read:

foreach (var x in someValues)
{
    list.Add(x + 1);
}

If you're adamant you want an Linq style extension. it's trivial to implement this yourself.

public static void ForEach<T>(this IEnumerable<T> @this, Action<T> action)
{
   foreach (var x in @this)
      action(x);
}

When you generate a JAXB model from an XML Schema, global elements that correspond to named complex types will have that metadata captured as an @XmlElementDecl annotation on a create method in the ObjectFactory class. Since you are creating the JAXBContext on just the DocumentType class this metadata isn't being processed. If you generated your JAXB model from an XML Schema then you should create the JAXBContext on the generated package name or ObjectFactory class to ensure all the necessary metadata is processed.

Example solution:

JAXBContext jaxbContext = JAXBContext.newInstance(my.generatedschema.dir.ObjectFactory.class);
DocumentType documentType = ((JAXBElement<DocumentType>) jaxbContext.createUnmarshaller().unmarshal(inputStream)).getValue();

This will give you all property names and values defined in your dynamic variable.

dynamic d = { // your code };
object o = d;
string[] propertyNames = o.GetType().GetProperties().Select(p => p.Name).ToArray();
foreach (var prop in propertyNames)
{
    object propValue = o.GetType().GetProperty(prop).GetValue(o, null);
}

The difference is primarily in deployment. Web forward and reverse proxies all have the same underlying features. They accept requests for HTTP requests in various formats and provide a response, usually by accessing the origin or contact server.

Fully featured servers usually have access control, caching, and some link-mapping features.

A forward proxy is a proxy that is accessed by configuring the client machine. The client needs protocol support for proxy features (redirection, proxy authentication, etc.). The proxy is transparent to the user experience, but not to the application.

A reverse proxy is a proxy that is deployed as a web server and behaves like a web server, with the exception that instead of locally composing the content from programs and disk, it forwards the request to an origin server. From the client perspective it is a web server, so the user experience is completely transparent.

In fact, a single proxy instance can run as a forward and reverse proxy at the same time for different client populations.

Add labels to each argument in your plot call corresponding to the series it is graphing, i.e. label = "series 1"

Then simply add Pyplot.legend() to the bottom of your script and the legend will display these labels.

Use jQuery. Keep your checkbox elements hidden and create a list like this:

<ul id="list">
    <li><a href="javascript:void(0)" id="link1">Happy face</a></li>
    <li><a href="javascript:void(0)" id="link2">Sad face</a></li>
</ul>

<form action="file.php" method="post">
    <!-- More code -->
    <input type="radio" id="option1" name="radio1" value="happy" style="display:none"/>
    <input type="radio" id="option2" name="radio1" value="sad" style="display:none"/>
    <!-- More code -->
</form>

<script type="text/javascript">
$("#list li a").click(function() {
    $('#list .active').removeClass("active");
    var id = this.id;
    var newselect = id.replace('link', 'option');
    $('#'+newselect).attr('checked', true);
    $(this).addClass("active").parent().addClass("active");
    return false;
});
</script>

This code would add the checked attribute to your radio inputs in the background and assign class active to your list elements. Do not use inline styles of course, don't forget to include jQuery and everything should run out of the box after you customize it.

Cheers!

Here's a solution for those that may still be struggling. You want to add a mouseover event on the 'parent' element of the child element(s) you want detected. The below code shows you how to go about it.

const wrapper = document.getElementById('wrapper') //parent element
const position = document.getElementById("displaySelection")

wrapper.addEventListener('mousemove', function(e) {
  let elementPointed = document.elementFromPoint(e.clientX, e.clientY)

  console.log(elementPointed)
});

Note: I found this question (varchar(255) v tinyblob v tinytext), which says that VARCHAR(n) requires n+1 bytes of storage for n<=255, n+2 bytes of storage for n>255. Is this the only reason? That seems kind of arbitrary, since you would only be saving two bytes compared to VARCHAR(256), and you could just as easily save another two bytes by declaring it VARCHAR(253).

No. you don't save two bytes by declaring 253. The implementation of the varchar is most likely a length counter and a variable length, nonterminated array. This means that if you store "hello" in a varchar(255) you will occupy 6 bytes: one byte for the length (the number 5) and 5 bytes for the five letters.

Oracle 11 G and 12 C versions suggest to use more complex passwords, Although there is no issues during the user creation. The password must be alphanumeric and with special character.

Verify the password version and status of the user:

select * from dba_users where username = <user_name>;

Amend it to be like below in case of 11G 12C:

alter user <user_name> identified by Pass2019$;

Now test connection!

Might be of help for someone else facing the same issue.You can load the file as string and then can convert the string to jsonobject to access the values.

import java.util.Scanner;
import org.json.JSONObject;
String myJson = new Scanner(new File(filename)).useDelimiter("\\Z").next();
JSONObject myJsonobject = new JSONObject(myJson);

I re-installed node through this link and it fixed it.

I think the issue was that I somehow got node to be in my /usr/bin instead of /usr/local/bin.

No, unless you want to break compatibility and your compiler supports it.

If you don't want to check on upper or lowercases you can use the following method.

String str = "India" 
compareString(str) 

def compareString(String str){ 
  def str2 = "india" 
  if( str2.toUpperCase() == str.toUpperCase() ) { 
    println "same" 
  }else{ 
    println "not same" 
  } 
}

So now if you change str to "iNdIa" it'll still work, so you lower the chance that you make a typo.

A hash table totally works on the fact that practical computation follows random access machine model i.e. value at any address in memory can be accessed in O(1) time or constant time.

So, if I have a universe of keys (set of all possible keys that I can use in a application, e.g. roll no. for student, if it's 4 digit then this universe is a set of numbers from 1 to 9999), and a way to map them to a finite set of numbers of size I can allocate memory in my system, theoretically my hash table is ready.

Generally, in applications the size of universe of keys is very large than number of elements I want to add to the hash table(I don't wanna waste a 1 GB memory to hash ,say, 10000 or 100000 integer values because they are 32 bit long in binary reprsentaion). So, we use this hashing. It's sort of a mixing kind of "mathematical" operation, which maps my large universe to a small set of values that I can accomodate in memory. In practical cases, often space of a hash table is of the same "order"(big-O) as the (number of elements *size of each element), So, we don't waste much memory.

Now, a large set mapped to a small set, mapping must be many-to-one. So, different keys will be alloted the same space(?? not fair). There are a few ways to handle this, I just know the popular two of them:

• Use the space that was to be allocated to the value as a reference to a linked list. This linked list will store one or more values, that come to reside in same slot in many to one mapping. The linked list also contains keys to help someone who comes searching. It's like many people in same apartment, when a delivery-man comes, he goes to the room and asks specifically for the guy.
• Use a double hash function in an array which gives the same sequence of values every time rather than a single value. When I go to store a value, I see whether the required memory location is free or occupied. If it's free, I can store my value there, if it's occupied I take next value from the sequence and so on until I find a free location and I store my value there. When searching or retreiving the value, I go back on same path as given by the sequence and at each location ask for the vaue if it's there until I find it or search all possible locations in the array.

I am a git newbie as well. I had the same problem with 'your branch is ahead of origin/master by N commits' messages. Doing the suggested 'git diff origin/master' did show some diffs that I did not care to keep. So ...

Since my git clone was for hosting, and I wanted an exact copy of the master repo, and did not care to keep any local changes, I decided to save off my entire repo, and create a new one:

(on the hosting machine)

mv myrepo myrepo
git clone USER@MASTER_HOST:/REPO_DIR myrepo

For expediency, I used to make changes to the clone on my hosting machine. No more. I will make those changes to the master, git commit there, and do a git pull. Hopefully, this should keep my git clone on the hosting machine in complete sync.

To use the default system proxies (e.g. from the http_support environment variable), the following works for the current request (without installing it into urllib2 globally):

url = 'http://www.example.com/'
proxy = urllib2.ProxyHandler()
opener = urllib2.build_opener(proxy)
in_ = opener.open(url)
in_.read()

Also be aware that when converting from numeric string ie '56.72' to INT you may come up against a SQL error.

Conversion failed when converting the varchar value '56.72' to data type int.

To get around this just do two converts as follows:

STRING -> NUMERIC -> INT

or

SELECT CAST(CAST (MyVarcharCol AS NUMERIC(19,4)) AS INT)

When copying data from TableA to TableB, the conversion is implicit, so you dont need the second convert (if you are happy rounding down to nearest INT):

INSERT INTO TableB (MyIntCol)
SELECT CAST(MyVarcharCol AS NUMERIC(19,4)) as [MyIntCol]
FROM TableA

I see you have already gotten a lot of answers, but if you are looking for a regular expression that can match integers and floating point numbers, this one will work for you:

var reg = /^-?\d*\.?\d+$/;

•   is the character entity reference (meant to be easily parseable by humans).
•   is the numeric entity reference (meant to be easily parseable by machines).

They are the same except for the fact that the latter does not need another lookup table to find its actual value. The lookup table is called a DTD, by the way.

You can read more about character entity references in the offical W3C documents.

It don't create normally; you need to add it by yourself.

After adding Global.asax by

• Right clicking your website -> Add New Item -> Global Application Class -> Add

You need to add a class

• Right clicking App_Code -> Add New Item -> Class -> name it Global.cs -> Add

Inherit the newly generated by System.Web.HttpApplication and copy all the method created Global.asax to Global.cs and also add an inherit attribute to the Global.asax file.

Your Global.asax will look like this: -

<%@ Application Language="C#" Inherits="Global" %>

Your Global.cs in App_Code will look like this: -

public class Global : System.Web.HttpApplication
{
    public Global()
    {
        //
        // TODO: Add constructor logic here
        //
    }

    void Application_Start(object sender, EventArgs e)
    {
        // Code that runs on application startup

    }
    /// Many other events like begin request...e.t.c, e.t.c
}

test1.endIndex gives the same result as test1.characters.count on Swift 3

The first commenter (R Samuel Klatchko) referenced: What are the rules about using an underscore in a C++ identifier? which answers the question about the underscore in C++. In general, you are not supposed to use a leading underscore, as it is reserved for the implementer of your compiler. The code you are seeing with _var is probably either legacy code, or code written by someone that grew up using the old naming system which didn't frown on leading underscores.

As other answers state, it used to be used in C++ to identify class member variables. However, it has no special meaning as far as decorators or syntax goes. So if you want to use it, it will compile.

I'll leave the C# discussion to others.

If DFS finds an edge that points to an already-visited vertex, you have a cycle there.

git pull origin master

this will sync your master to the central repo and if new branches are pushed to the central repo it will also update your clone copy.

Below is the method that worked for me on API 23-25 emulators. The explanation is provided for API 24 but works almost identically for other versions.

Credits: Jon Doe, zaidorx, pjl.

Warm advice for readers: please just go over the steps before following them, as some are automated via provided scripts.

1. In the AVD manager of Android studio (tested on v2.2.3), create a new emulator with the "Android 7.0 (Google APIs)" target:

2. Download the latest Open GApps package for the emulator's architecture (CPU/ABI). In my case it was x86_64, but it can be something else depending on your choice of image during the device creation wizard. Interestingly, the architecture seems more important than the correct Android version (i.e. gapps for 6.0 also work on a 7.0 emulator).

3. Extract the .apk files using from the following paths (relative to open_gapps-x86_64-7.0-pico-201#####.zip):

   .zip\Core\gmscore-x86_64.tar.lz\gmscore-x86_64\nodpi\priv-app\PrebuiltGmsCore\
   .zip\Core\gsfcore-all.tar.lz\gsfcore-all\nodpi\priv-app\GoogleServicesFramework\
   .zip\Core\gsflogin-all.tar.lz\gsflogin-all\nodpi\priv-app\GoogleLoginService\
   .zip\Core\vending-all.tar.lz\vending-all\nodpi\priv-app\Phonesky\
   

   Note that Open GApps use the Lzip compression, which can be opened using either the tool found on the Lzip website^1,2, or on Mac using homebrew: brew install lzip. Then e.g. lzip -d gmscore-x86_64.tar.lz.

   I'm providing a batch file that utilizes 7z.exe and lzip.exe to extract all required .apks automatically (on Windows):

   @echo off
   echo.
   echo #################################
   echo Extracting Gapps...
   echo #################################
   7z x -y open_gapps-*.zip -oGAPPS
   
   echo Extracting Lzips...
   lzip -d GAPPS\Core\gmscore-x86_64.tar.lz
   lzip -d GAPPS\Core\gsfcore-all.tar.lz
   lzip -d GAPPS\Core\gsflogin-all.tar.lz
   lzip -d GAPPS\Core\vending-all.tar.lz
   
   move GAPPS\Core\*.tar
   
   echo. 
   echo #################################
   echo Extracting tars...
   echo #################################

   echo.

   del *.tar
   
   echo.
   echo #################################
   echo All done! Press any key to close.
   echo #################################
   pause>nul
   

   To use this, save the script in a file (e.g. unzip_gapps.bat) and put everything relevant in one folder, as demonstrated below:

4. Update the su binary to be able to modify the permissions of the files we will later upload. A new su binary can be found in the SuperSU by Chainfire package "Recovery flashable" zip. Get the zip, extract it somewhere, create the a batch file with the following contents in the same folder, and finally run it:

   adb root
   adb remount
   
   adb push eu.chainfire.supersu_2.78.apk /system/app/
   adb push x64/su /system/xbin/su
   adb shell chmod 755 /system/xbin/su
   
   adb shell ln -s /system/xbin/su /system/bin/su
   adb shell "su --daemon &"
   adb shell rm /system/app/SdkSetup.apk
   

5. Put all .apk files in one folder and create a batch file with these contents³:

   START /B E:\...\android-sdk\tools\emulator.exe @Nexus_6_API_24 -no-boot-anim -writable-system
   adb wait-for-device
   adb root
   adb shell stop
   adb remount
   adb push PrebuiltGmsCore.apk /system/priv-app/PrebuiltGmsCore
   adb push GoogleServicesFramework.apk /system/priv-app/GoogleServicesFramework
   adb push GoogleLoginService.apk /system/priv-app/GoogleLoginService
   adb push Phonesky.apk /system/priv-app/Phonesky/Phonesky.apk
   adb shell su root "chmod 777 /system/priv-app/**"
   adb shell su root "chmod 777 /system/priv-app/PrebuiltGmsCore/*"
   adb shell su root "chmod 777 /system/priv-app/GoogleServicesFramework/*"
   adb shell su root "chmod 777 /system/priv-app/GoogleLoginService/*"
   adb shell su root "chmod 777 /system/priv-app/Phonesky/*"
   adb shell start
   

   Notice that the path E:\...\android-sdk\tools\emulator.exe should be modified according to the location of the Android SDK on your system.

6. Execute the above batch file (the console should look like this afterwards):

   O:\123>START /B E:\...\android-sdk\tools\emulator.exe @Nexus_6_API_24 -no-boot-anim -writable-system
   
   O:\123>adb wait-for-device
   Hax is enabled
   Hax ram_size 0x60000000
   HAX is working and emulator runs in fast virt mode.
   emulator: Listening for console connections on port: 5554
   emulator: Serial number of this emulator (for ADB): emulator-5554
   
   O:\123>adb root
   
   O:\123>adb shell stop
   
   O:\123>adb remount
   remount succeeded
   
   O:\123>adb push PrebuiltGmsCore.apk /system/priv-app/PrebuiltGmsCore/
   [100%] /system/priv-app/PrebuiltGmsCore/PrebuiltGmsCore.apk
   
   O:\123>adb push GoogleServicesFramework.apk /system/priv-app/GoogleServicesFramework/
   [100%] /system/priv-app/GoogleServicesFramework/GoogleServicesFramework.apk
   
   O:\123>adb push GoogleLoginService.apk /system/priv-app/GoogleLoginService/
   [100%] /system/priv-app/GoogleLoginService/GoogleLoginService.apk
   
   O:\123>adb push Phonesky.apk /system/priv-app/Phonesky/Phonesky.apk
   [100%] /system/priv-app/Phonesky/Phonesky.apk
   
   O:\123>adb shell su root "chmod 777 /system/priv-app/**"
   
   O:\123>adb shell su root "chmod 777 /system/priv-app/PrebuiltGmsCore/*"
   
   O:\123>adb shell su root "chmod 777 /system/priv-app/GoogleServicesFramework/*"
   
   O:\123>adb shell su root "chmod 777 /system/priv-app/GoogleLoginService/*"
   
   O:\123>adb shell su root "chmod 777 /system/priv-app/Phonesky/*"
   
   O:\123>adb shell start
   

7. When the emulator loads - close it, delete the Virtual Device and then create another one using the same system image. This fixes the unresponsive Play Store app, "Google Play Services has stopped" and similar problems. It works because in the earlier steps we have actually modified the system image itself (take a look at the Date modified on android-sdk\system-images\android-24\google_apis\x86_64\system.img). This means that every device created from now on with the system image will have gapps installed!

8. Start the new AVD. If it takes unusually long to load, close it and instead start it using:

   START /B E:\...\android-sdk\tools\emulator.exe @Nexus_6_API_24
   adb wait-for-device
   adb shell "su --daemon &"
   

   After the AVD starts you will see the image below - notice the Play Store icon in the corner!

³ - I'm not sure all of these commands are needed, and perhaps some of them are overkill... it seems to work - which is what counts. :)

How a character is represented is up to the renderer, but the server may also strip out certain characters before sending the document.

You can also have untitled YouTube videos like https://www.youtube.com/watch?v=dmBvw8uPbrA by using the Unicode character ZERO WIDTH NON-JOINER (U+200C), or ‌ in HTML. The code block below should contain that character:

?? 

I had to map FAKE/REAL to 0/1 but couldn't find proper answer.

Please find below how to map column name 'type' which has values FAKE/REAL to 0/1
(Note: similar can be applied to any column name and values)

df.loc[df['type'] == 'FAKE', 'type'] = 0
df.loc[df['type'] == 'REAL', 'type'] = 1

If this persists even after clearing provisioning profile and re-downloading them, then it might be due to the bundle ID already registered in Apple's MDM push certificate.

<location path="ControllerName/ActionName">
    <system.web>
        <httpRuntime executionTimeout="1000"/>
    </system.web>
</location>

Probably it is better to set such values in web.config instead of controller. Hardcoding of configurable options is considered harmful.

If desired to make this behavior, always show a small prefix on the input field or the user can't erase a prefix:

   // prefix="prefix_text"
   // If the user changes the prefix, restore the input with the prefix:
   if(document.getElementById('myInput').value.substring(0,prefix.length).localeCompare(prefix))
       document.getElementById('myInput').value = prefix;

Parsing a string representation of a DateTime is a tricky thing because different cultures have different date formats. .Net is aware of these date formats and pulls them from your current culture (System.Threading.Thread.CurrentThread.CurrentCulture.DateTimeFormat) when you call DateTime.Parse(this.Text);

For example, the string "22/11/2009" does not match the ShortDatePattern for the United States (en-US) but it does match for France (fr-FR).

Now, you can either call DateTime.ParseExact and pass in the exact format string that you're expecting, or you can pass in an appropriate culture to DateTime.Parse to parse the date.

For example, this will parse your date correctly:

DateTime.Parse( "22/11/2009", CultureInfo.CreateSpecificCulture("fr-FR") );

Of course, you shouldn't just randomly pick France, but something appropriate to your needs.

What you need to figure out is what System.Threading.Thread.CurrentThread.CurrentCulture is set to, and if/why it differs from what you expect.

A static method is one type of method which doesn't need any object to be initialized for it to be called. Have you noticed static is used in the main function in Java? Program execution begins from there without an object being created.

Consider the following example:

 class Languages 
 {
     public static void main(String[] args) 
     {
         display();
     }

     static void display() 
     {
         System.out.println("Java is my favorite programming language.");
     }
  }

Laravel Server Requirements mention that BCMath, Ctype, JSON, Mbstring, OpenSSL, PDO, Tokenizer, and XML extensions are required. Most of the extensions are installed and enabled by default.

You can run the following command in Ubuntu to make sure the extensions are installed.

sudo apt install openssl php-common php-curl php-json php-mbstring php-mysql php-xml php-zip

PHP version specific installation (if PHP 7.4 installed)

sudo apt install php7.4-common php7.4-bcmath openssl php7.4-json php7.4-mbstring

You may need other PHP extensions for your composer packages. Find from links below.

PHP extensions for Ubuntu 20.04 LTS (Focal Fossa)

PHP extensions for Ubuntu 18.04 LTS (Bionic)

PHP extensions for Ubuntu 16.04 LTS (Xenial)

document.location is an object, while document.location.href is a string. But the former has a toString method, so you can read from it as if it was a string and get the same value as document.location.href.

In some browsers - most modern ones, I think - you can also assign to document.location as if it were a string. According to the Mozilla documentation however, it is better to use window.location for this purpose as document.location was originally read-only and so may not be as widely supported.

jQuery('#main').css('opacity') = '0.6';

should be

jQuery('#main').css('opacity', '0.6');

Update:

http://jsfiddle.net/GegMk/ if you type in the text box. Click away, the opacity changes.

To make the image move right:

float: right;

To make the text not wrapped:

clear: right;

For best practice, put the css code in your stylesheets file. Once you add more code, it will look messy and hard to edit.

I think you're looking for this:

elements = [10, 11, 12, 13, 14, 15]
indices = (1,1,2,1,5)

result_list = [elements[i] for i in indices]    

HttpClientFactory

It's important to evaluate the different ways you can create an HttpClient, and part of that is understanding HttpClientFactory.

https://docs.microsoft.com/en-us/dotnet/architecture/microservices/implement-resilient-applications/use-httpclientfactory-to-implement-resilient-http-requests

This is not a direct answer I know - but you're better off starting here than ending up with new HttpClient(...) everywhere.

I was having the same issue and tried all of the solutions on this page but none of them did the trick.

What finally worked was adding the universe repo to my repo list. To do that run the following command

sudo add-apt-repository universe

After running the above command I was able to run

sudo apt install openjdk-8-jre

without an issue and the package was installed.

Hope this helps someone.

For more complex layouts I often used GridBagLayout, which is more complex, but that's the price. Today, I would probably check out MiGLayout.

This is how I do it:

CSS:

html, body {
    margin: 0;
    padding: 0;
    width: 100%;
    height: 100%;
    display: table
}
#content {
    display: table-cell;
    text-align: center;
    vertical-align: middle
}

HTML:

<div id="content">
    Content goes here
</div>

See

Example of vertical centering

and

CSS: centering things.

You can send the FormData object in ajax request using the following code,

$("form#formElement").submit(function(){
    var formData = new FormData($(this)[0]);
});

This is very similar to the accepted answer but an actual answer to the question topic. This will submit the form elements automatically in the FormData and you don't need to manually append the data to FormData variable.

The ajax method looks like this,

$("form#formElement").submit(function(){
    var formData = new FormData($(this)[0]);
    //append some non-form data also
    formData.append('other_data',$("#someInputData").val());
    $.ajax({
        type: "POST",
        url: postDataUrl,
        data: formData,
        processData: false,
        contentType: false,
        dataType: "json",
        success: function(data, textStatus, jqXHR) {
           //process data
        },
        error: function(data, textStatus, jqXHR) {
           //process error msg
        },
});

You can also manually pass the form element inside the FormData object as a parameter like this

var formElem = $("#formId");
var formdata = new FormData(formElem[0]);

Hope it helps. ;)

NODE_ENV is an environmental variable that stands for node environment in express server.

It's how we set and detect which environment we are in.

It's very common using production and development.

Set:

export NODE_ENV=production

Get:

You can get it using app.get('env')

None of the answers here show idiomatic functional programming. The recursive factorial answer is great for representing recursion in FP, but the majority of code is not recursive so I don't think that answer is fully representative.

Say you have an arrays of strings, and each string represents an integer like "5" or "-200". You want to check this input array of strings against your internal test case (Using integer comparison). Both solutions are shown below

Procedural

arr_equal(a : [Int], b : [Str]) -> Bool {
    if(a.len != b.len) {
        return false;
    }

    bool ret = true;
    for( int i = 0; i < a.len /* Optimized with && ret*/; i++ ) {
        int a_int = a[i];
        int b_int = parseInt(b[i]);
        ret &= a_int == b_int;  
    }
    return ret;
}

Functional

eq = i, j => i == j # This is usually a built-in
toInt = i => parseInt(i) # Of course, parseInt === toInt here, but this is for visualization

arr_equal(a : [Int], b : [Str]) -> Bool =
    zip(a, b.map(toInt)) # Combines into [Int, Int]
   .map(eq)
   .reduce(true, (i, j) => i && j) # Start with true, and continuously && it with each value

While pure functional languages are generally research languages (As the real-world likes free side-effects), real-world procedural languages will use the much simpler functional syntax when appropriate.

This is usually implemented with an external library like Lodash, or available built-in with newer languages like Rust. The heavy lifting of functional programming is done with functions/concepts like map, filter, reduce, currying, partial, the last three of which you can look up for further understanding.

Addendum

In order to be used in the wild, the compiler will normally have to work out how to convert the functional version into the procedural version internally, as function call overhead is too high. Recursive cases such as the factorial shown will use tricks such as tail call to remove O(n) memory usage. The fact that there are no side effects allows functional compilers to implement the && ret optimization even when the .reduce is done last. Using Lodash in JS, obviously does not allow for any optimization, so it is a hit to performance (Which isn't usually a concern with web development). Languages like Rust will optimize internally (And have functions such as try_fold to assist && ret optimization).

My problem was the location of the config file.

In eclipse settings (Windows->preferences->maven->User Settings) the default config file for maven points to C:\users\*yourUser*\.m2\settings.xml. If you unzip maven and install it in a folder of your choice the file will be inside *yourMavenInstallDir*/conf/, thus probably not where eclipse thinks (mine was not). If this is the case maven won't load correctly. You just need to set the "User Settings" path to point to the right file.

Accessing a name and assigning a name are different. In your case, you are just accessing a name.

If you assign to a variable within a function, that variable is assumed to be local unless you declare it global. In the absence of that, it is assumed to be global.

>>> x = 1         # global 
>>> def foo():
        print x       # accessing it, it is global

>>> foo()
1
>>> def foo():   
        x = 2        # local x
        print x 

>>> x            # global x
1
>>> foo()        # prints local x

Inline elements can't be transformed, and pseudo elements are inline by default, so you must apply display: block or display: inline-block to transform them:

#whatever:after {
  content: "\24B6";
  display: inline-block;
  transform: rotate(30deg);
}

<div id="whatever">Some text </div>

I ran across this while on a hunt for answers myself after attempting to follow a guide using pm2. The goal is to automatically start a node.js application on a server. Some guides call out using pm2 startup systemd, which is the path that leads to the question of using systemctl on Ubuntu 14.04. Instead, use pm2 startup ubuntu.

Source: https://www.digitalocean.com/community/tutorials/how-to-set-up-a-node-js-application-for-production-on-ubuntu-14-04

var obj = [
  {"name": "Afghanistan", "code": "AF"}, 
  {"name": "Åland Islands", "code": "AX"}, 
  {"name": "Albania", "code": "AL"}, 
  {"name": "Algeria", "code": "DZ"}
];

// the code you're looking for
var needle = 'AL';

// iterate over each element in the array
for (var i = 0; i < obj.length; i++){
  // look for the entry with a matching `code` value
  if (obj[i].code == needle){
     // we found it
    // obj[i].name is the matched result
  }
}

In addition to the answers above the command below will also work. I post it because it makes more sense to me. In each case it is 'using x-value-column: y-value-column'

plot 'ls.dat' using 1:2, 'ls.dat' using 1:3, 'ls.dat' using 1:4 

note that the command above assumes that you have a file named ls.dat with tab separated columns of data where column 1 is x, column 2 is y1, column 3 is y2 and column 4 is y3.

The graphicx package provides the command \resizebox{width}{height}{object}:

\documentclass{article}
\usepackage{graphicx}
\begin{document}
\hrule
%%%
\makeatletter%
\setlength{\@tempdima}{\the\columnwidth}% the, well columnwidth
\settowidth{\@tempdimb}{(\ref{Equ:TooLong})}% the width of the "(1)"
\addtolength{\@tempdima}{-\the\@tempdimb}% which cannot be used for the math
\addtolength{\@tempdima}{-1em}%
% There is probably some variable giving the required minimal distance
% between math and label, but because I do not know it I used 1em instead.
\addtolength{\@tempdima}{-1pt}% distance must be greater than "1em"
\xdef\Equ@width{\the\@tempdima}% space remaining for math
\begin{equation}%
\resizebox{\Equ@width}{!}{$\displaystyle{% to get everything inside "big"
 A+B+C+D+E+F+G+H+I+J+K+L+M+N+O+P+Q+R+S+T+U+V+W+X+Y+Z}$}%
\label{Equ:TooLong}%
\end{equation}%
\makeatother%
%%%

\end{document}

$(function () {
    //declare function 
    $.fn.myfunction = function () {
        return true;
    };
});

$(document).ready(function () {
    //call function
    $("#my_div").myfunction();
});

The Key Disappears, whether it is numeric or not. Try out the test script below.

<?php
    $t = array( 'a', 'b', 'c', 'd' );
    foreach($t as $k => $v)
        echo($k . ": " . $v . "<br/>");
    // Output: 0: a, 1: b, 2: c, 3: d

    unset($t[1]);

    foreach($t as $k => $v)
        echo($k . ": " . $v . "<br/>");
    // Output: 0: a, 2: c, 3: d
?>

I found the solution as follows:

private void gridView1_RowCellClick(object sender, DevExpress.XtraGrid.Views.Grid.RowCellClickEventArgs e)
{
    TBGRNo.Text = gridView1.GetRowCellValue(gridView1.FocusedRowHandle, "GRNo").ToString();
    TBSName.Text = gridView1.GetRowCellValue(gridView1.FocusedRowHandle, "SName").ToString();
    TBFName.Text = gridView1.GetRowCellValue(gridView1.FocusedRowHandle, "FName").ToString();            
}

You can also type

cat /build.info

This will give you an output like this

BUILD_BRANCH=master
BUILD_COMMIT=434160726dacc4a1a592fe6036891d6e646a3a4a
BUILD_TIME=2017-05-12T16:02:04Z

Configuring the CORS response headers on the server wasn't really an option. You should configure a proxy in client side.

Sample to Angular - So, I created a proxy.conf.json file to act as a proxy server. Below is my proxy.conf.json file:

{
  "/api": {
    "target": "http://localhost:49389",
    "secure": true,
    "pathRewrite": {
      "^/api": "/api"
    },
    "changeOrigin": true
  }
}

Put the file in the same directory the package.json then I modified the start command in the package.json file like below

"start": "ng serve --proxy-config proxy.conf.json"

now, the http call from the app component is as follows:

return this.http.get('/api/customers').map((res: Response) => res.json());

Lastly to run use npm start or ng serve --proxy-config proxy.conf.json

The answer from Constantin is spot on but for more background this behavior is inherited from Matlab.

The Matlab behavior is explained in the Figure Setup - Displaying Multiple Plots per Figure section of the Matlab documentation.

subplot(m,n,i) breaks the figure window into an m-by-n matrix of small subplots and selects the ithe subplot for the current plot. The plots are numbered along the top row of the figure window, then the second row, and so forth.

You can have a Windows 10 configuration with and without Hyper-V as follows in an Admin prompt:

bcdedit /copy {current} /d "Windows 10 no Hyper-V"

find the new id of the just created "Windows 10 no Hyper-V" bootentry, eg. {094a0b01-3350-11e7-99e1-bc5ec82bc470}

bcdedit /set {094a0b01-3350-11e7-99e1-bc5ec82bc470} hypervisorlaunchtype Off

After rebooting you can choose between Windows 10 with and without Hyper-V at startup

A lot of people have answered this already, but I thought it might be useful to share the function I wrote that strips HTML tags from a string but allows you to include an array of tags that you do not want stripped. It's pretty short and has been working nicely for me.

function removeTags(string, array){
  return array ? string.split("<").filter(function(val){ return f(array, val); }).map(function(val){ return f(array, val); }).join("") : string.split("<").map(function(d){ return d.split(">").pop(); }).join("");
  function f(array, value){
    return array.map(function(d){ return value.includes(d + ">"); }).indexOf(true) != -1 ? "<" + value : value.split(">")[1];
  }
}

var x = "<span><i>Hello</i> <b>world</b>!</span>";
console.log(removeTags(x)); // Hello world!
console.log(removeTags(x, ["span", "i"])); // <span><i>Hello</i> world!</span>

Disclaimer: As of early 2015, there is a great comparison of IoC Container features from Jimmy Bogard, here is a summary:

Compared Containers:

• Autofac
• Ninject
• Simple Injector
• StructureMap
• Unity
• Windsor

The scenario is this: I have an interface, IMediator, in which I can send a single request/response or a notification to multiple recipients:

public interface IMediator 
{ 
    TResponse Send<TResponse>(IRequest<TResponse> request);

    Task<TResponse> SendAsync<TResponse>(IAsyncRequest<TResponse> request);

    void Publish<TNotification>(TNotification notification)
        where TNotification : INotification;

    Task PublishAsync<TNotification>(TNotification notification)
        where TNotification : IAsyncNotification; 
}

I then created a base set of requests/responses/notifications:

public class Ping : IRequest<Pong>
{
    public string Message { get; set; }
}
public class Pong
{
    public string Message { get; set; }
}
public class PingAsync : IAsyncRequest<Pong>
{
    public string Message { get; set; }
}
public class Pinged : INotification { }
public class PingedAsync : IAsyncNotification { }

I was interested in looking at a few things with regards to container support for generics:

• Setup for open generics (registering IRequestHandler<,> easily)
• Setup for multiple registrations of open generics (two or more INotificationHandlers)

Setup for generic variance (registering handlers for base INotification/creating request pipelines) My handlers are pretty straightforward, they just output to console:

public class PingHandler : IRequestHandler<Ping, Pong> { /* Impl */ }
public class PingAsyncHandler : IAsyncRequestHandler<PingAsync, Pong> { /* Impl */ }

public class PingedHandler : INotificationHandler<Pinged> { /* Impl */ }
public class PingedAlsoHandler : INotificationHandler<Pinged> { /* Impl */ }
public class GenericHandler : INotificationHandler<INotification> { /* Impl */ }

public class PingedAsyncHandler : IAsyncNotificationHandler<PingedAsync> { /* Impl */ }
public class PingedAlsoAsyncHandler : IAsyncNotificationHandler<PingedAsync> { /* Impl */ }

You can use it like this:

$(document).ready(function(){

    setTimeout("swapImages()",1000);

    function swapImages(){

        var active = $('.active'); 
        var next = ($('.active').next().length > 0) ? $('.active').next() : $('#siteNewsHead img:first');

        active.removeClass('active');
        next.addClass('active');
        setTimeout("swapImages()",1000);
}

});

Simpler with the aggregate function string_agg() (Postgres 9.0 or later):

SELECT movie, string_agg(actor, ', ') AS actor_list
FROM   tbl
GROUP  BY 1;

The 1 in GROUP BY 1 is a positional reference and a shortcut for GROUP BY movie in this case.

string_agg() expects data type text as input. Other types need to be cast explicitly (actor::text) - unless an implicit cast to text is defined - which is the case for all other character types (varchar, character, "char"), and some other types.

As isapir commented, you can add an ORDER BY clause in the aggregate call to get a sorted list - should you need that. Like:

SELECT movie, string_agg(actor, ', ' ORDER BY actor) AS actor_list
FROM   tbl
GROUP  BY 1;

But it's typically faster to sort rows in a subquery. See:

• Postgres SQL - Create Array in Select

Have a look at iconv() or mb_convert_encoding(). Just by the way: why don't utf8_encode() and utf8_decode() work for you?

utf8_decode — Converts a string with ISO-8859-1 characters encoded with UTF-8 to single-byte ISO-8859-1

utf8_encode — Encodes an ISO-8859-1 string to UTF-8

So essentially

$utf8 = 'ÄÖÜ'; // file must be UTF-8 encoded
$iso88591_1 = utf8_decode($utf8);
$iso88591_2 = iconv('UTF-8', 'ISO-8859-1', $utf8);
$iso88591_2 = mb_convert_encoding($utf8, 'ISO-8859-1', 'UTF-8');

$iso88591 = 'ÄÖÜ'; // file must be ISO-8859-1 encoded
$utf8_1 = utf8_encode($iso88591);
$utf8_2 = iconv('ISO-8859-1', 'UTF-8', $iso88591);
$utf8_2 = mb_convert_encoding($iso88591, 'UTF-8', 'ISO-8859-1');

all should do the same - with utf8_en/decode() requiring no special extension, mb_convert_encoding() requiring ext/mbstring and iconv() requiring ext/iconv.

I had a similar issue. Rather than run the search through the dom every time though the loop for the select control I saved the jquery select element in a variable and did this:

function isValueInSelect($select, data_value){
    return $($select).children('option').map(function(index, opt){
        return opt.value;
    }).get().includes(data_value);
}

In your handler, check the window.event object for the property ctrlKey as such:

function selectMe(){
    if (window.event.ctrlKey) {
        //ctrl was held down during the click
    }
}

UPDATE: the above solution depends on a proprietary property on the window object, which perhaps should not be counted on to exist in all browsers. Luckily, we now have a working draft that takes care of our needs, and according to MDN, it is widely supported. Example:

HTML

<span onclick="handler(event)">Click me</span>

JS

function handler(ev) {
  console.log('CTRL pressed during click:', ev.ctrlKey);
}

The same applies for keyboard events

See also KeyboardEvent.getModifierState()

For Win32 DOS, you can:

c:> dir /s c:\directory\you\want

and the penultimate line will tell you how many bytes the files take up.

I know this reads all files and directories, but works faster in some situations.

if (variable) can be used if variable is guaranteed to be an object, or if false, 0, etc. are considered "default" values (hence equivalent to undefined or null).

typeof variable == 'undefined' can be used in cases where a specified null has a distinct meaning to an uninitialised variable or property. This check will not throw and error is variable is not declared.

insert into OPT (email, campaign_id) 
select '[email protected]',100
from dual
where not exists(select * 
                 from OPT 
                 where (email ='[email protected]' and campaign_id =100));

To complete answers in case of editing default value :

In your rails console :

rails g migration MigrationName

In the migration :

  def change
    change_column :tables, :field_name, :field_type, default: value
  end

Will look like :

  def change
    change_column :members, :approved, :boolean, default: true
  end

Try This:

$url = "http://www.google.com/search?q=".$strSearch."&hl=en&start=0&sa=N";
  $ch = curl_init();
  curl_setopt($ch, CURLOPT_HEADER, 0);
  curl_setopt($ch, CURLOPT_VERBOSE, 0);
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
  curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible;)");
  curl_setopt($ch, CURLOPT_URL, urlencode($url));
  $response = curl_exec($ch);
  curl_close($ch);

Alternatively, you could override your spinner adapter, and provide an empty view for position 0 in your getView method, and a view with 0dp height in the getDropDownView method.

This way, you have an initial text such as "Select an Option..." that shows up when the spinner is first loaded, but it is not an option for the user to choose (technically it is, but because the height is 0, they can't see it).

You shouldn't be setting the value of the input through refs.

Take a look at the documentation for controlled form components here - https://facebook.github.io/react/docs/forms.html#controlled-components

In a nutshell

<input value={this.state.value} onChange={(e) => this.setState({value: e.target.value})} />

Then you will be able to control the disabled state by using disabled={!this.state.value}

Another solution I ran across tonight, which worked for my needs, was to add box-sizing attributes:

-webkit-box-sizing: border-box;
-moz-box-sizing: border-box;
box-sizing: border-box;

These attributes force the border to be part of the box model's width and height and correct the issue as well.

According to caniuse.com » box-sizing, box-sizing is supported in IE8+.

If you're using LESS or Sass there is a Bootstrap mixin for this.

LESS:

.box-sizing(border-box);

Sass:

@include box-sizing(border-box);

Here's how i am calling my modal

    console.log($(e.relatedTarget).data('id')); // 190 will be printed
});

If none of given solutions fixed the error, the issue probably about Google Cloud Billing settings. You must enable Billing on the Google Cloud Project at billing/enable.

Tables work differently; sometimes counter-intuitively.

The solution is to use width on the table cells instead of max-width.

Although it may sound like in that case the cells won't shrink below the given width, they will actually.
with no restrictions on c, if you give the table a width of 70px, the widths of a, b and c will come out as 16, 42 and 12 pixels, respectively.
With a table width of 400 pixels, they behave like you say you expect in your grid above.
Only when you try to give the table too small a size (smaller than a.min+b.min+the content of C) will it fail: then the table itself will be wider than specified.

I made a snippet based on your fiddle, in which I removed all the borders and paddings and border-spacing, so you can measure the widths more accurately.

table {_x000D_
  width: 70px;_x000D_
}_x000D_
_x000D_
table, tbody, tr, td {_x000D_
  margin: 0;_x000D_
  padding: 0;_x000D_
  border: 0;_x000D_
  border-spacing: 0;_x000D_
}_x000D_
_x000D_
.a, .c {_x000D_
  background-color: red;_x000D_
}_x000D_
_x000D_
.b {_x000D_
  background-color: #F77;_x000D_
}_x000D_
_x000D_
.a {_x000D_
  min-width: 10px;_x000D_
  width: 20px;_x000D_
  max-width: 20px;_x000D_
}_x000D_
_x000D_
.b {_x000D_
  min-width: 40px;_x000D_
  width: 45px;_x000D_
  max-width: 45px;_x000D_
}_x000D_
_x000D_
.c {}

<table>_x000D_
  <tr>_x000D_
    <td class="a">A</td>_x000D_
    <td class="b">B</td>_x000D_
    <td class="c">C</td>_x000D_
  </tr>_x000D_
</table>

You can create config once and use it everywhere.

const instance = axios.create({
  baseURL: 'https://some-domain.com/api/',
  timeout: 1000,
  headers: {'Authorization': 'Bearer '+token}
});

instance.get('/path')
.then(response => {
    return response.data;
})

Spent some time working on a solution to my issue and thought it may be of interest. I ran into a problem trying to automate code generation using PowerShell 3.0 on Windows 8. The target IDE was the Keil compiler using MDK-ARM Essential Toolchain 5.24.1. A bit different from OP, as I am using PowerShell natively during the pre-build step. When I tried to #include the generated file, I received the error

fatal error: UTF-16 (LE) byte order mark detected '..\GITVersion.h' but encoding is not supported

I solved the problem by changing the line that generated the output file from:

out-file -FilePath GITVersion.h -InputObject $result

to:

out-file -FilePath GITVersion.h -Encoding ascii -InputObject $result

For your needs, use ConcurrentHashMap. It allows concurrent modification of the Map from several threads without the need to block them. Collections.synchronizedMap(map) creates a blocking Map which will degrade performance, albeit ensure consistency (if used properly).

Use the second option if you need to ensure data consistency, and each thread needs to have an up-to-date view of the map. Use the first if performance is critical, and each thread only inserts data to the map, with reads happening less frequently.

You can use Joda time library for Java. It would be much easier to calculate time-diff between dates with it.

Sample snippet for time-diff:

Days d = Days.daysBetween(startDate, endDate);
int days = d.getDays();

Go via POSIXct and you want to set a TZ there -- here you see my (Chicago) default:

R> val <- 1352068320
R> as.POSIXct(val, origin="1970-01-01")
[1] "2012-11-04 22:32:00 CST"
R> as.Date(as.POSIXct(val, origin="1970-01-01"))
[1] "2012-11-05" 
R> 

Edit: A few years later, we can now use the anytime package:

R> library(anytime)
R> anytime(1352068320)
[1] "2012-11-04 16:32:00 CST"
R> anydate(1352068320)
[1] "2012-11-04"
R> 

Note how all this works without any format or origin arguments.

use :

char ch=**scanner.nextChar**()

Presumably, since you're not providing a value for the DB_ID column, that value is being populated by a row-level before insert trigger defined on the table. That trigger, presumably, is selecting the value from a sequence.

Since the data was moved (presumably recently) from the production database, my wager would be that when the data was copied, the sequence was not modified as well. I would guess that the sequence is generating values that are much lower than the largest DB_ID that is currently in the table leading to the error.

You could confirm this suspicion by looking at the trigger to determine which sequence is being used and doing a

SELECT <<sequence name>>.nextval
  FROM dual

and comparing that to

SELECT MAX(db_id)
  FROM cmdb_db

If, as I suspect, the sequence is generating values that already exist in the database, you could increment the sequence until it was generating unused values or you could alter it to set the INCREMENT to something very large, get the nextval once, and set the INCREMENT back to 1.

As an example, mocha would normally be a devDependency, since testing isn't necessary in production, while express would be a dependency.

#include <windows.h>

double PCFreq = 0.0;
__int64 CounterStart = 0;

void StartCounter()
{
    LARGE_INTEGER li;
    if(!QueryPerformanceFrequency(&li))
    cout << "QueryPerformanceFrequency failed!\n";

    PCFreq = double(li.QuadPart)/1000.0;

    QueryPerformanceCounter(&li);
    CounterStart = li.QuadPart;
}
double GetCounter()
{
    LARGE_INTEGER li;
    QueryPerformanceCounter(&li);
    return double(li.QuadPart-CounterStart)/PCFreq;
}

int main()
{
    StartCounter();
    Sleep(1000);
    cout << GetCounter() <<"\n";
    return 0;
}

This program should output a number close to 1000 (windows sleep isn't that accurate, but it should be like 999).

The StartCounter() function records the number of ticks the performance counter has in the CounterStart variable. The GetCounter() function returns the number of milliseconds since StartCounter() was last called as a double, so if GetCounter() returns 0.001 then it has been about 1 microsecond since StartCounter() was called.

If you want to have the timer use seconds instead then change

PCFreq = double(li.QuadPart)/1000.0;

to

PCFreq = double(li.QuadPart);

or if you want microseconds then use

PCFreq = double(li.QuadPart)/1000000.0;

But really it's about convenience since it returns a double.

It's not a matter of deep copy or shallow copy, none of what you're doing is deep copy.

Here:

>>> new = original 

you're creating a new reference to the the list/dict referenced by original.

while here:

>>> new = original.copy()
>>> # or
>>> new = list(original) # dict(original)

you're creating a new list/dict which is filled with a copy of the references of objects contained in the original container.

It depends what is the character and what encoding it is in:

• An ASCII character in 8-bit ASCII encoding is 8 bits (1 byte), though it can fit in 7 bits.

• An ISO-8895-1 character in ISO-8859-1 encoding is 8 bits (1 byte).

• A Unicode character in UTF-8 encoding is between 8 bits (1 byte) and 32 bits (4 bytes).

• A Unicode character in UTF-16 encoding is between 16 (2 bytes) and 32 bits (4 bytes), though most of the common characters take 16 bits. This is the encoding used by Windows internally.

• A Unicode character in UTF-32 encoding is always 32 bits (4 bytes).

• An ASCII character in UTF-8 is 8 bits (1 byte), and in UTF-16 - 16 bits.

• The additional (non-ASCII) characters in ISO-8895-1 (0xA0-0xFF) would take 16 bits in UTF-8 and UTF-16.

That would mean that there are between 0.03125 and 0.125 characters in a bit.
